Gilastro
A complete sucker, fool, or chump. It is an emphatic variation of the word "gil", used for someone who is incredibly naive or slow-witted. (In Argentina, "gil" is the standard term for a naive person or a loser).
You are a Gilastro, your wife ran away with a cop (In Argentina, "pitufo" refers to a police officer because of their blue uniforms).
